Glendowie - 1st Certified Passive House in New Zealand

Underhill house - 1st in the UK

A COOLHOUSE is an architecturally designed, low energy, premium, prefabricated home.

A COOLHOUSE combines the best passive house or low energy technologies from overseas with local award-winning design and green home construction.

A COOLHOUSE combines stunning design, an international standard of building, off-site manufacturing techniques and precision construction.

__ It’s quick and efficient – construction timelines are shortened due to European methods of offsite construction. The structure is up, airtight and watertight within 7 days and fully completed within 12 weeks (from slab going down).

__ It has superior strength, superior insulation, no mould or mildew.

__ We can construct to our client’s desired levels of energy efficiency, savings on utility bills of up to 80% can be achieved.

__ It’s warm in the winter/cool in the summer. A temperature of 18-24 degrees in every room, year round at a healthy humidity. This is achieved with virtually no active heating or cooling.

__ The protected building envelope means the insulation properties will not break down and will insulate to 100% of its value for the life of the building.

__ We have over 20 years of experience and knowledge in both design and low energy construction methods.

__ COOLHOUSE reflects a passion for providing New Zealanders with architecturally designed homes that are affordable and have proven energy efficiency – without compromising on style.

__ Our off-site manufactured homes are of exceptional quality, with excellent thermal efficiency and air-tightness.

__ The long term benefits of a low energy coolhouse is a healthier, sustainable and durable home which enhances future living standards.

“COOLHOUSE will bea New Zealand Standard”

There is a major shift worldwide toward sustainable, green and low energy architecture.

COOLHOUSE is New Zealand’s answer to this movement, designing affordable, stylish and low energy houses.

performance standard

not a design standard...”

While a Passive House building does not need to be certified to be considered a Passive House, certification provides an important and visible form of quality assurance.

To ensure Passive House requirements are met, two pressure tests are normally scheduled while the project is onsite. The first test is performed once the airtight envelope is completed but still exposed. The second test, once works are complete, has to be carried out by a suitable qualified technician, independent from the construction team. This technician uses specialised software to measure the R value, air tightness, and thermal bridging performance of the design as well as assess the mechanical systems in place (air recovery ventilation, heating and cooling systems and hot water production.)

The starting cost for going through this process to becoming a Certified Passive Houses in New Zealand is around $5000 NZD.

Passive House Certification(an optional extra)

In a low energy or Passive House, the entire envelope of the building is well insulated - the walls, windows, roof and floor. This ensures that heat is not lost in winter and keeps indoor temperatures lower during the summertime.Cellulose under floor insulation-R 2.4Wool insulation in external walls-R 4.8Wool insulation in ceiling-R 6.2

A Heat Recovery Ventilation System (HRVS) ensures that fresh, good quality, even air is circulated throughout the house at a comfortable temperature. Heat is recovered from the warm, stale indoor air and passed to the cold, fresh incoming air, bringing it up to near room temperature. Further, to minimise the loss of heat through structures and windows, the combination of passive heating and heat recovery from ventilation air provides almost all of the heating.

The best investment to be made for a beautiful sustainable home is choosing thermally efficient windows and doors. Timber joinery is specified because timber is the ultimate renewable material, it requires much less energy to be processed and is a natural insulator which greatly enhances the thermal performance of a home. Our window and door profiles are made from the highest quality laminated wood profiles, tested and certified to European (the world’s most stringent) standards. We use double or triple glazing with low e glass and thermally insulated frames. Each sash has four full length weather seals (rubber to rubber) which ensures a perfect fit.

Site works generally include any excavation work, foundation preparation and drainage that is required before construction can commence . These works are site specific and vary depending on location, accessibility, slope and ground conditions.For this reason we are unable to estimate the cost of these however we are able to faciliate the undertakings of these works and coordinate with the relevant consultants and obtain the necessary consents if required.

Air Circulationwith heat recovery

Thermal bridges are points where heat can be transferred from one element to another. This heat transfer generally occurs between the floor slab and the ground, at corners, connections, windows and where insulation is interrupted. They lead to about 10-15% of the loss of heat in traditional buildings, so eliminating thermal bridges can significantly influence the thermal performance of a house. Through specific design of structural connections and by insulating under the flooring, thermal bridging can be practically eliminated. This ensures that the interior temperature of the building is not affected by the exterior conditions.

Airtightness describes how non-draughty the building structure is. Contrary to previous belief, it is now considered hugely important to achieve an airtight building envelope. Draughts are not only uncomfortable but can contribute to significant heat losses. Constructing an airtight building envelope improves sound protection and saves energy by ensuring that the ventilation system operates most efficiently. The airtight envelope is achieved by wrapping the whole building with 'Intello' variable humidity airtightness membrane (building paper). This includes placing membrane along all the connections between various building elements i.e between walls/window and walls/ceilings, taping all joins in the membrane and taping around all services that protrude through it.

Darren Jessop is an award-winning architect who is commited to excellence. He is the designer of Australasia’s first certified Passive House, which has recently claimed recognition and was selected as a finalist in the International Passive House Awards 2014. The look and feel of his architecture can be considered modern pacific rim with classic lines, resulting in timeless structures.

The inspiration for COOLHOUSE came about through Darren’s learning experience with Passive House construction techniques. COOLHOUSE was developed with the aim of improving the way homes are built in New Zealand and by enabling a healthy low energy (and low cost) way of living.

Darren believes that creative, cool design doesn’t need to be compromised when building a low energy home.

Greg has over 25 years of experience in the building industry. He believes that construction today is a “maze of legal, town planning, environmental and public interest issues that effect all projects one way or another”, and he provides an effective and coordinated management of all these issues. Each backed project follows strict building contracts that ensure a no stress program.
